Button with looped sound in AS 3.0, no auto start

Hi there.

Trying to make a series of interactive buttons in AS 3.0

The button needs to be able to do the following :

  • Does not start the MP3 loop automatically when the SWF is opened
  • On click, loops forever until the user clicks another MP3 looping button
  • Has up, over and down states

Any help on this would be great.

Thanks
